ABSTRACT:
A print head is moved to and fro between two direction reversing points along a print support and simultaneously moved forward toward the print support until the head engages the support. The engagement of the head with the support produces a variable parameter in response to the to and fro reciprocating movement. When the parameter reaches a given value indicating engagement of the head and support, the forward movement of the head is stopped, and the print head, starting from this position, in which the gap between the head and support is zero, is moved in the reverse direction away from the support to the desired gap value.
